HCID 205208691-[(5,6-dichloro-9a-methyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]cyclopentane-1-carboxylic acid

Procedure

Carrying out a reaction as described in Example 1, Step E, except that the ethyl [(5,6-dichloro-9a-ethyl-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetate is replaced by an equimolar quantity of ethyl 1-[(5,6-dichloro-9a-methyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]cyclopentane-1-carboxylate, to give 1-[(5,6-dichloro-9a-methyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]cyclopentane-1-carboxylic acid.
